[0003]

In the above-mentioned conventional example, the blindfold material (ceiling decoration edge) is simply a strip plate and has a poor three-dimensional effect, and the decorativeness of the corner portion cannot be improved.
Therefore, it is conceivable that the cross-sectional shape of this blindfold material is three-dimensionally formed, for example, in a triangular shape to improve the decorativeness of the corner portion. By the way, the blindfold material is made of a long material and is often stacked when storing and transporting it, and even in that case, warping, twisting, or other deformation does not occur, and it is necessary to maintain a regular shape. Desired. Further, the blind material made of a hard long material is fitted into the engaging groove of the edge by turning the protruding portion extending in the longitudinal direction with a hammer tool, but if the deformation is large, the attachment becomes difficult. Therefore, in consideration of such conditions, it is difficult to maintain the three-dimensional shape and prevent the deformation by simply forming the blindfold material in three dimensions.

Therefore, an object of the present invention is to provide a ceiling decorative edge which improves the decorativeness of the corner portion, maintains a three-dimensional shape, and does not cause deformation such as warp or twist even when stacked. .

[0005]

SUMMARY OF THE INVENTION To achieve the above object, the present invention provides a ceiling decorative edge to be attached to a corner portion of a wall panel and a ceiling panel, an upper surface portion facing at least the ceiling panel, and a slope portion facing the room. The hollow member is composed of a rib connecting the upper surface portion and the slope portion, and the rib is a soft material. Also,
The upper surface and the slope portion and the soft rib were integrally formed by a two-color molding method to form a ceiling decoration edge. Furthermore, the slope portion is a flat slope, a curved surface or a multi-step curved surface. Furthermore, a locking projection is formed at one end of the upper surface, and this is fitted to a joint that connects the wall panel and the ceiling panel.

[0006]

The ceiling decoration edge prevents deformation of the ceiling decoration edge by connecting the upper surface and the slope with a rib. Further, since the rib is made of a soft material, it has a lot of freedom, and even if deformation occurs, it can be corrected when it is attached to the corner portion.
